> That, to me, obviously signifies social which is what sharing is. Except that's not what sharing is at all. I can share a photograph with one person by just emailing it to them. We can even share a conversation that way. I can turn it into a group conversation by adding CC recipients. Or I can make it public by sending to a newsgroup instead of an email recipient. No social involved in any of those forms of sharing (although you could argue that Usenet is a social network). The public folder icon isn't inconsistent because the "share" icon represents an action (click this to share something), whereas the folder icon represents a state (the folder is public; there's nothing to click on).
